University of Chicago Medicine orthopaedic experts offer tailored solutions for treating knee pain that is caused by joint degeneration from osteoarthritis. Using advanced robotic arm-assisted technology, our surgeons can resurface areas of the knee while sparing healthy bone and ligaments. This less-invasive approach — when combined with a patient-specific surgical plan and more accurate partial knee implant placement — results in a more natural feeling knee compared with a total knee replacement.
This innovative approach, called Mako partial knee resurfacing, offers several benefits for patients with early- to mid-stage osteoarthritis pain that is not controlled by medication. Advantages include:
Before surgery, a CT scan is taken of the knee and is used to create a 3D anatomical model of the knee. This model allows the surgeon to more accurately plan the surgery, knee resurfacing and implant placement. During surgery, the orthopaedic surgeon guides the robotic arm to prepare bone for a knee implant. The robotic system aids the surgeon by ensuring that bone removal is confined to affected areas, stopping the robotic arm if necessary.
When a knee joint is injured or diseased, the ligaments, tendons and/or cartilage surrounding the knee bone can break down, causing bone-on-bone friction that can be damaging and painful. The image shows what a knee joint may like when a patient needs future treatment.
